What is Cat6 LSZH?

Cat6 LSZH Cable—High-Performance Data Cable Our Cat6 low-smoke zero-halogen (LSZH) cable consists of paired solid bare copper conductors, PE insulation, and an LSZH jacket. It has a maximum temperature rating of 60°C and may be used in current and next-generation applications using a bandwidth of 25 MHz.

Does Cat6 work better than Cat5?

Compared to Cat5/5e cables, Cat6 cables have stricter performance specifications and significant higher data transfer speeds at greater distances. They are more tightly wound than Cat5 cables, and the cable conductors and cable sheath are thicker as well.

Which is faster Cat5e or Cat 6?

Cat 6 is pricier and faster than Cat 5e, but also limited by distance. Cat 6 supports data transfer speeds up to 10 Gbps at 250 MHz with even less (or no) crosstalk interference, due to the cable’s improved insulation. However, its 10 Gbps speed is effective only up to 164 feet.

What is the difference between a cat5 and a CAT6 cable?

The difference between a Cat5 vs Cat6 cable is not only higher speeds but reduced “crosstalk”.

Is LSZH a good alternative to plenum rated cable?

As the two illustrations make clear, LSZH is no substitute for plenum rated cable. LSZH may be a safer alternative to outdoor (CMX) cable jackets being used indoors, but right now that is all it has going for it. Now, we know that LSZH does not live up to expectations in regards to spreading fire or the amount of smoke generated.

Why is CAT5 obsolete?

Cat5 has become obsolete in recent years, due to its limitations compared to Cat5E and Cat6 cables. Although the Cat5 cable can handle up to 10/100 Mbps at a 100MHz bandwidth (which was once considered quite efficient), the newer versions of Cat cables are faster.

What is an LSZH cable jacket?

In 1979, British Research Engineering developed the LSZH cable jacket (Low Smoke Zero Halogen) for use in commercial plenum spaces, submarines, and nuclear power plants. This jacket type was developed in and used by European countries and further adopted by Asian countries.
